Very long ago, there was an American president who needed to travel by sea for an extended period of time. He preferred being a vegetarian. During the travel, he managed to eat vegetarian food for the first couple of days. As he watched his fellow travelers eat fish, he was swayed by it. His mind then thought of the logic stating ‘God created all beings to support one another, that is why the food pyramid exists. Thus, it’s okay to eat fish now’. After he reached the destination, he put his mind into work again to support his desire to go back to being vegetarian. So his mind found another logic stating, ‘we need not eat meat when we can survive comfortably on plant food’.
